Abstract
La presente solicitud se refiere a técnicas para autenticacion flujos de datos. Específicamente, la solicitud se refiere a la insercion de identificadores dentro de un flujo de datos, tal como una serie de bits en el tiempo Pulso Dolby, AAC o HE AAC, y la autenticacion y verificacion del flujo de datos en base tales identificadores. Se describe un método y un sistema para codificar un flujo de datos que comprende una pluralidad de cuadros de datos. El método comprende el paso de generar un valor criptográfico del numero N de cuadros de datos sucesivos e informacion de configuracion, en donde la informacion de configuracion comprende informacion para reproducir los datos. El método luego inserta el valor criptográfico dentro del flujo de datos subsiguiente a los N cuadros de datos sucesivos.
